Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Casio EX-ZR15 and Nikon 1 AW1 side-by-side from the front, back and top in their relative dimensions. Casio EX-ZR15 has external dimensions of 102 x 59 x 27 mm (4.02 x 2.32 x 1.06″) and weighs 176 g (0.39 lb / 6.21 oz) (including batteries). Nikon 1 AW1 has external dimensions of 114 x 72 x 37 mm (4.47 x 2.81 x 1.46″) and weighs 356 g (0.78 lb / 12.6 oz) (including batteries).
Below you can see the front-view size comparison of the Casio EX-ZR15 and the Nikon 1 AW1. Casio EX-ZR15 is clearly the smaller of the two cameras. Its body is 12mm narrower, 13mm shorter and 10mm thinner than Nikon 1 AW1. As you can tell, actually this is not a fair size comparison since Casio EX-ZR15 has a built-in lens but Nikon 1 AW1 doesn't. Once you put a lens on 1 AW1, its thickness will increase significantly.
Here is the back view size comparison of the Casio EX-ZR15 and Nikon 1 AW1.
Now lets look at the top view comparison of Casio EX-ZR15 and Nikon 1 AW1.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Casio EX-ZR15 is significantly lighter (180g ) than the Nikon 1 AW1 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on 1 AW1, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather-sealed body of the 1 AW1, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to the EX-ZR15.
LCD Screen Size and Features
Casio EX-ZR15 and Nikon 1 AW1's LCD screens have the same diagonal size of 3.00 inches.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
